Weighted vs unweighted GPA: how do they differ?
An unweighted GPA scores every class on the same 4.0 scale, so an A is a 4.0 in gym and in AP Chemistry. A weighted GPA adds bonus points for harder classes, usually 0.5 for honors and 1.0 for AP, IB or dual enrollment, so it can go above 4.0 and often tops out at 5.0. Each school sets its own weights.
In more detail
Unweighted GPA answers one question: what grades did you earn? Weighted GPA answers a second one: how hard were the classes behind those grades? Schools that weight give the extra points as a flat bump per course level, so a B in an AP class (3.0 + 1.0 = 4.0) counts the same as an A in a regular class.
Your transcript may show one of the two or both, and the legend or the school profile says which. Weights are not standard: some schools add 0.5 for honors and 1.0 for AP, some cap the scale at 4.5, and some do not weight at all. If your school reports only one number, ask your counselor which it is before you quote it.
Colleges do not simply take your number. Many recalculate GPA with their own formula, often counting only core academic classes and dropping the extra weight, and they read your grades next to your school's profile to see which classes were on offer. Check each college's admissions page for how it handles weighted GPAs.

Step by step
- 1
Take four one-credit classes: English (regular) with an A, Algebra II (honors) with a B, AP Biology with an A and Spanish (regular) with a B.
- 2
Unweighted: an A is 4.0 and a B is 3.0, so 4.0 + 3.0 + 4.0 + 3.0 = 14.0. Divide by 4 classes and you get a 3.50.
- 3
Weighted, with 0.5 extra for honors and 1.0 for AP: 4.0 + 3.5 + 5.0 + 3.0 = 15.5.
- 4
Divide 15.5 by 4 classes and you get 3.875, which rounds to 3.88.
- 5
Same grades, two numbers. Quote the one your transcript labels, and say which one it is.

More questions
Do colleges prefer a weighted or an unweighted GPA?
Neither by default. Many colleges recalculate your GPA with their own formula, often on core academic classes only, and read it next to your school's profile. Check the admissions page of each college you apply to.
Is a 4.5 GPA weighted or unweighted?
It is almost certainly weighted. An unweighted GPA tops out at 4.0, so any number above that comes from extra points for honors, AP, IB or dual enrollment classes.
